Estonian composer Arvo Pärt likened his music to white light that contained all colors, and saw “the spirit of the listener” as the prism where those colors could appear. Lincoln Center’s White Light Festival is dedicated to exploring that intersection between art and spirit across a number of disciplines. This year’s event includes a comic interpretation of Samuel Beckett’s Waiting for Godot from Ireland’s Druid theater company; Blak Whyte Gray from East London’s Boy Blue, an abstract work that mixes hip-hop dance with African-inspired grooves and an electronic score; and the US premiere of Kaija Saariaho’s chamber opera Only the Sound Remains, based on two Noh plays translated by Ezra Pound and directed by Peter Sellars.
